The opening sequence presents electronic music hardware along with electronic sounds, the video starts of with in introduction by F.RBMoore of the Bell telephone laboratories going on to talk about electronic music influences that made electronic music possible, going on to talk about the functions of the hardware through Dr. Gerald Strang, of the University of California Los Angeles explaining the complexities of electronic music, and the differences that electronic music has compared to the way traditional instrumental music is composed.
They then present examples of real instruments, and the sounds of the melodies comparing the sounds and showing how the sounds can be adapted and changed, presenting the wave formats involved and their differences that are controlled through the oscillator, and the electronic synthesiser. They then show the different waves that can be changed, and what methods can be used be cutting from the keyboard to jack outlets and the on screen monitor waveform, to a guy playing a musical melody from the electronic synthesizer and transitioning to how enveloping works. Starting With the sounds of a jet they filter and remove sounds making the sound into a melody through the work of the synthesizer. They then show how to envelope by adding a sharp attack and slow decay with the sound of the chellow, they then give several more examples doing the same but by imitating the sounds of a Koto, and trumpet. After they cut to nature and a cloudy sky as it rains on a garden, and futs back to droplets falling from the plans and birds chirping, and cutting to a man playing the synthesizer as he changes the sounds playing Bach on the piano keyboard, explaining how the synthesizer picks up the sounds through a microphone and altering the sounds from the different waveforms cutting to many different musicians playing other instruments--and all of them playing at the same time. They then cut to more hardware as they explain how technology can process faster than humans, and connecting to envelope generator and the oscillator. The computer tells the artist the melody in computer language that us to be played, and from there the computer can manipulate the direction of melody pitch and weather to play it hard soft or fast and slow with representation on the monitor as it cuts to a person controlling these functions through a mixer. All these sounds create images on the monitor, ending the program with circular and intricate imagery of sound reflected on the monitor, and a presentation of the electronic instruments and hardware that make these sounds.
